5009‐ppi, 10000‐cd/m2, OLED/OS/Si structure display with built‐in CPU and display driver

Journal of the Society for Information Display, Volume 33, Issue 5, Page 314-323, May 2025.
This study developed a 5,009‐ppi, 10,000‐cd/m2 organic light‐emitting diode display featuring c‐axis‐aligned crystalline oxide semiconductor field‐effect transistors (FETs) monolithically stacked over silicon (Si) FETs. It was demonstrated that a built‐in central processing unit (Cortex‐M0) enables amplifier offset compensation and that functional ...

Influence of the clamping force on the power cycling lifetime reliability of press pack IGBT sub‐module

The Journal of Engineering, Volume 2019, Issue 16, Page 2435-2439, March 2019., 2019
The clamping force is the most important parameter of Press Pack IGBTs (PP IGBTs) as it not only affects the electrical, thermal, and mechanical characteristic, but also the long lifetime reliability. Too little clamping force increases the contact resistance and junction temperature.

Large Area Epitaxial Lateral Overgrowth of Semipolar (11¯$1 \left(\right. \macr \left.\right)$01) GaN Stripes on Patterned Si Substrates Prepared using Maskless Lithography

physica status solidi (b), Volume 261, Issue 11, November 2024.
The growth of semipolar (11¯01$1101 \left(\right. \macr \left.\right)$) GaN stripes and InGaN LED structure on patterned Si substrate is demonstrated by applying mature Si processing techniques. This method enables the large‐scale Si substrate patterning required for semipolar GaN growth and is expected to be applied to the mass production of semipolar

Bionic boron/silicon‐modified phenolic resin system with multifunctional groups: synthesis, thermal properties and ablation mechanism

Biosurface and Biotribology, Volume 4, Issue 3, Page 85-93, September 2018., 2018
A kind of silicon‐and‐boron‐modified phenolic–formaldehyde resin (SBPF) with excellent thermal stability was fabricated via a simple two‐step method and used for the matrix of ablation materials. The structure and thermal stability of the modified phenolic–formaldehyde resins (PFs) were characterised.

Surface Photovoltage Spectroscopy as a Valuable Tool for Evaluating Oxidation Processes in the Microelectronics Industry

physica status solidi (a), Volume 221, Issue 17, September 2024.
The minority carrier diffusion length (MCDL) and the flat band voltage, determined by surface photovoltage spectroscopy measurements, are compared in n‐ and p‐type Si wafers after oxidation under different conditions using various tools (horizontal and vertical furnaces, atomic layer deposition (ALD), low‐pressure chemical vapor deposition, and plasma ...

Natural‐air‐cooled 5 kVA single‐phase GaN inverter with paralleled multilayer PCB magnetics

The Journal of Engineering, Volume 2018, Issue 2, Page 94-103, February 2018., 2018
In this study, a systematic approach to the design and development of a high‐efficiency, natural‐air‐cooled, single‐phase inverter with a multilayer high‐current printed‐circuit board (PCB) magnetics is presented. The size and efficiency of inverters implemented with the silicon transistor technology have almost reached a certain limit. The use of wide
